For example, the product puller finds use in moving a product located thereon forward or backward relative to a front edge of a shelf or storage unit.

The present application claims priority to and the benefit of U.S. Provisional Application No. 60/316,694, filed Oct. 7, 2004, which is incorporated herein by reference in its entirety.

BACKGROUND

The present disclosure relates, in various exemplary embodiments, to an apparatus for conveying or moving items or products located near a rear portion of a shelf or storage unit toward a front portion thereof. The present disclosure also relates to a method for using such an apparatus, which can be termed a product puller. A product puller finds particular application in a retail or warehouse-type store, and will be described with reference thereto. However, the product puller is suitable in any environment where it is desirable to store or display items on a shelf or in a storage unit where the product may prove difficult to access.

Goods or products for sale at both retail stores and wholesale warehouse type stores are often displayed for sale on or in shelves of a storage unit. There is probably an unlimited number of items that may be displayed in such a manner, including, for example, diapers, household items, packages of food, clothing, and the like. As items are shopped and removed from the shelves, items near the back or rearward portion of the shelf may be difficult to reach, and in some instances even difficult to view. This may be the case in particular where the items are located on a high shelf or a relatively deep shelf. Additionally, it may be difficult to reach or obtain a single product located near the back of a shelf where several products are stacked on top of one another.

In view of the foregoing, it is desirable to provide an apparatus for use in a shelving unit by which a single item or a plurality of items that are positioned near the rear or back portion of a shelf may be conveyed or moved forward toward the front of the shelving unit and thereby made accessible for retrieval and/or viewing by a shopper, store employee, or the like.

DETAILED DESCRIPTION

Generally, a product puller according to the instant disclosure comprises a sheet or sheet-like structure having a top, exposed surface, a bottom surface, and a means for moving the sheet or sheet-like structure in a forward or backward direction relative to a front portion of a shelf or shelving unit. The top surface, which may also be referred to as the support surface of a product puller is suitable for supporting one or more items such as, for example, packages, containers, boxes, or the like. The bottom surface, or at least a portion thereof, contacts another surface, such as the surface of a shelf, and can be slidable or moveable in relation to the shelf. In certain embodiments, the support surface of the sheet can be substantially planar. The product puller is suitable for use in a shelving environment and allows for items resting or placed on the support surface of the sheet to be moved along the shelf in either a forward direction, toward a front portion of the shelf, or in a rearward direction, toward a rear portion of the shelf, as the sheet is moved.

With reference to FIGS. 1-6, product pullers according to first, second, and third exemplary embodiments are shown. With reference to FIGS. 1-6, a sheet-like product puller 10 includes a top exposed surface 12, which also may be referred to as the support surface, a bottom surface 14, a forward portion 16, and a rear portion 17. Adjacent the rear portion 17, the product puller 10 includes a product backstop 18, which can be triangular in shape. Product backstop 18 of product puller 10 includes a forward facing wall 20 braced by an angled wall 24. A foot or flap 23 of the forward facing wall 20 can be suitably secured to the sheet top surface 12. Forward wall 20 of product backstop 18 is adapted for contacting at least one rearwardly located item or product supported by or placed on the support surface 12.

The shape or configuration of product backstop 18 is not critical and not limited in any manner except to the extent that the product backstop provides a wall or surface which is suitable for contacting at least a portion of one or more products or items supported on the surface of the product puller. Product backstop 18 may be attached or connected to the product puller 10 in any suitable manner including, but not limited to by an adhesive, sink welding, stapling, other known fasteners, or the like. For example, backstop 18 can be a rear end of the product puller 10 which is folded over and is attached by sink welding a flap 23 to the surface 12. However, the product backstop may be a separate structure that is attached to the product puller or may be formed directly as part of the product puller configuration, such as by molding. In one embodiment, it can be a portion of the product puller structure that is configured to form a backstop such as by folding at pre-selected creases or folds.

The product puller 10 can also include a hand hold, such as a slot 28, which can be located adjacent the forward portion 16 thereof. In this embodiment, the slot 28 is generally sized and shaped to allow a person to fit one or more fingers in the slot in order to grasp the product puller and move the product puller in a desired direction. The size and shape of slot 28, and its location, are otherwise not limited in any matter.

A product puller may also comprise various structures or mounting means for mounting a sheet member to an associated shelf. With reference to FIGS. 2 and 2A, for example, a product puller may be mounted between product dividers. In FIGS. 2 and 2A, product puller 10 is disposed between product dividers 11 a and 11 b, which would generally be mounted or disposed on a shelf. As shown in FIGS. 2 and 2A, product divider 11 a and 11 b have the same configuration. Referring to product divider 11 a, the product dividers in this embodiment have a generally vertical wall or member 13 a and generally horizontal walls 15 a and 19 a, which may be generally perpendicular to the vertical wall 13 a. Product puller 10 is disposed between generally horizontal wall 19 a of product divider 11 a and generally horizontal wall 15 b of product divider 11 b.

In one embodiment (not shown), a product puller may be disposed between generally horizontal walls of opposing product dividers such that the bottom surface of a product puller is in contact with a shelf surface. In another embodiment, such as shown in FIG. 2A, the bottom surface 14 of product puller 10 may contact the top surfaces of the generally horizontal walls, such as walls 19 a and 15 b.

The shape, configuration, and height of product dividers may be selected as desired for a particular purpose or intended use. Additionally, the product dividers may be formed from any material including, but not limited to, metals, plastics, composites, and the like. The product dividers may be formed or molded single-piece structures or formed by separately connected pieces.

It will be appreciated that a product divider may include one or two generally horizontal walls. The use of product dividers with two generally horizontal walls facing in opposite directions relative to the general vertical wall allows for a single product divider to separate adjacent sheet members.

With reference now to FIGS. 3 and 4, a product puller assembly can also include a tether system 30 to maintain the product puller 10 in a particular position on the shelf and/or aid in retracting the sheet-like structure of the product puller toward the rearward portion of the shelf/storage unit. In this embodiment, the tether system 30 performs a retractive function such that, after being moved in a forward direction toward a front portion of a shelf, the product puller may be retracted toward the rear portion of the shelf. In the embodiment of FIGS. 3 and 4, tether system 30 includes a tether storage box 32, a tether 34 selectively wound into and out of the box (such as on a spool, not visible), and a mounting bracket 38 to which the storage box 32 can be secured. As is well known in the art, a resilient element, such as a spring can bias a spool rotatably mounted in the tether storage box in order to wind the tether into the box. An end of the tether can be secured to the spool in a known manner. However, the strength of the spring can be weak enough such that it will not retract the product puller 10 if there are any packages held on it. When there are no packages located on the product puller, the tether can be wound back onto the spool and into the storage box 32. At the same time, the product puller can be repositioned away from a front edge of the shelf, as is illustrated in FIGS. 3 and 4.

To tether the product puller 10, an attachment piece 36 is mounted to a rear portion of the product puller. With respect to FIGS. 3 and 4, the attachment piece 36 can include a barb which is mounted to the backstop 18 of the product puller 10 by inserting the barb through a hole 26 in, for example, the angled wall 24. Attachment piece 36 is not limited in any manner and may be any suitable structure that is capable of attaching tether 34 to the product puller 10 including, but not limited to, a barb, prong, fastener, snap, button, tie, or the like. The tether, such as tether 34, is not critical and may be any structure suitable as a tether including, but not limited to, a spring, a string, chord, cable, chain, wire, strap, band, or the like. The tether system 30 may be mounted to the rear portion of the shelf either directly or, as shown in FIG. 3, by mounting the storage box 32 via an adhesive 33 on a surface of the storage box 32 to a formed box mounting bracket 38 which is adapted to clip on to a portion of a shelf.

With reference now to FIG. 5, in another embodiment, mounting bracket 38′ may include a stop member to limit the rearward travel of a product puller. With reference to FIGS. 5 and 6, mounting bracket 38′ includes a stop member 37. The stop member 37 is shown as in the form of a loop or arch. A stop member, however, may be of any shape or height as desired for a particular purpose or intended use. Additionally, the stop member may be a solid block structure. The stop member may be made from any suitable material, including, metals, plastics, composites, and the like.

It will be appreciated that various systems may be combined to form a product puller apparatus. For example, in one embodiment a product puller could employ a sheet member, product dividers, and a tether system.

With reference to FIGS. 7 and 8, product puller 10 is shown in a shelving environment. In FIG. 7, bottom surface (not shown) of product puller 10 rests on rods 41 which form the support surface of shelf 40. Product puller 10 supports products or items 44 on top surface 12 of product puller 10. As shown in the left hand side of FIG. 7 items 44, which are supported on product puller 10, are located near the rear portion of shelf 40. Such items 44 can be moved toward the front portion of shelf 40, as depicted on the right hand side of FIG. 7, by grasping product puller 10 via slot 28, and pulling or otherwise applying a force to move product puller 10 in the direction P1. Alternatively, products or items 44 on product puller 10 may be moved away from the front portion of shelf 40 toward the rear portion there by applying a force in the direction P2.

As shown in FIG. 7, a backstop 18′ is different in form than backstop 18 illustrated in FIGS. 1-6 and 8. In this embodiment, the backstop is cylindrical and can be secured to a rear end by any known attachment means. Alternatively, the backstop can be simply an enlarged rear end of the product puller. As previously mentioned, the backstop can assume a variety of forms.

Product puller 10 is moved on shelf 40 by sliding the bottom surface of the shut member along the shelf surface. Such a product puller may be used in any shelving system and is not limited by shelf type. For example product puller 10 may be used on a solid shelf surface, a frame or screen shelf surface, or a shelf surface comprised of slats, rods, or tubes running either perpendicular to or horizontally to the front and rear edges of a shelf. To this end, the product puller 10 can be made of a material that includes a relatively slidable lower surface, such as polytetrafluoraethylene or another suitable conventional material. Also, the product puller 10 can be made from a flexible material if so desired.

With reference to FIG. 8, the use of product puller 10 is shown in a shopping or warehouse environment. Section A represents a fully loaded shelf comprising a plurality of items or products. As the items or products are removed from the shelf, as depicted by the removal of the first two vertical rows of items near the front edge 42 of the shelf, other items or products remain near the back portion of the shelf. As shown in Section B of FIG. 8, the last two vertical rows of products or items are supported by product puller 10. As the items are shopped or removed from the shelves such that the fully loaded shelf in Section A comes to resemble the half loaded shelf in Section B, the products or items supported by product puller 10 may be moved forward to the position represented by Section C by pulling or moving the product puller toward the front portion of the shelving unit.

With reference to FIGS. 9-12, a second exemplary embodiment of a product puller is shown. With reference to FIG. 9, a product puller 46 comprises a top, exposed or product support surface 48, a bottom surface 50, and product backstop 54. Product puller 46 can also includes slots or holes 52 which may be used to advance the product puller 46 toward a front portion of a shelf. Slots or holes 52 can be sized to accommodate at least one finger of a user who is trying to advance the product puller 46. The system can also include a support body 60. Support body 60 defines a slot-like opening 61 located near the upper portion thereof communicating with a hollow interior 62. The support body 60 can be located adjacent a front edge 82 (FIG. 11) of a shelf. Support body 60 may be positioned along the shelf by any suitable means to hold the support body in place, including, for example by an adhesive, fasteners, clips, and the like.

In the embodiment shown in FIGS. 9-12, end panels 64 a, 64 b are shaped to mate with respective ends of support body 60. End panels 64 a, 64 b define an overhanging portion 66 a, 66 b that is sized or adapted to fit over a top surface of a shelving beam, such as beam 82 (FIG. 12), to effectively clip the support body 60 onto a shelf. In other embodiments, the product puller 46, and particularly the support body 60, may be further secured to a shelf by one or more hold down brackets 70 a, 70 b, which define an opening adapted to fit or mate with the underside of a shelf beam, and is attached to the end panels 64 a, 64 b of the support body. The brackets can be attached to the end panels by any suitable known means, including, for example, an adhesive, a fastener, or the like. In the embodiment of FIGS. 9 and 10, hold down brackets 70 a, 70 b are attached to end panels 64 a, 64 b by fasteners 74 a, 74 b, which are inserted through aligned holes 72 a, 72 b in the hold down brackets and holes 70 a, 70 b in end panels 68 a, 68, respectively.

Support body 60 may include other optional items for display purposes. For example, support body 60 may include a C-channel 76 adapted to hold a graphic display, ticket holder, such as ticket holder 78, or the like.

With reference now to FIG. 11, products 84 are supported on the product puller 46. Such products may be advanced toward the front edge 82 of the shelf by grasping one of the holes 52 and applying a force, such as, for example, by pulling, to move product puller 46 in a direction P3 toward the front portion of a shelf 80. As product puller 46 is advanced forward in the direction P3, the sheet-like structure passes through opening 61 of support body 60 and winds in the interior 62 of the support body. If desired, the product puller 46 can be made of conventional material that is self-coiling so that it rolls up on itself within the interior 62 of support body 60. That is, the product puller feeds into the front mounted support body. The self-coiling action of the product puller 46 can be weaker than the weight of a package 84 held thereon so that the product puller will not wind into the support body 60 unless a person pulls it forward, such as by using holes 52.

The product puller 46 can have a length, including the length of the product backstop that is less than, equal to, or greater than the depth of the shelf. It will be appreciated that product puller 46 can be employed with a tether system, such as, for example, tether system 30 shown in FIGS. 5 and 6, to hold the product puller in a particular position transversely on the shelf and/or to resist the self-coiling action of the product puller 46 as it retracts into the support body 60.

It is noted that a backstop 54 in FIGS. 11 and 12 is different in form from backstop 54 shown in FIGS. 9 and 10. As previously mentioned, the backstop can assume a variety of forms. In this embodiment, the backstop is cylindrical and can be secured to a rear end of the product puller 46 by any known attachment means. Also, the backstop can be simply an enlarged rear end of the product puller, if so desired.

With reference to FIGS. 13-19, another embodiment of a product puller is shown. In this embodiment, a product puller 86 includes an endless belt 87 that is fitted over a plurality of rollers. To this end, rollers 100 and 101 mount the belt 87 in a frame including frame sides 88. The frame can be sized to fit between the front and rear beams of a conventional shelving unit. As shown in FIG. 13, a rear flange 94 can be adapted to rest on a rear beam 122 of a shelving unit, and a cut out portion 90 near the front of the frame is adapted to fit over a front beam 120 of a shelving unit. Frame sides 88 are separated by spacer tubes 92 which can be held in place by connecting threaded rods 96 and lock nuts 98. The frame sides 88 can also include a flange 89 that forms a top surface of each of the frame sides. Rollers 100 are positioned on the frames by pins 99. The frame can also include a front cover 116 to which can be mounted a display type item such as a tag 118.

Belt 87 includes an outer surface 87 a that is exposed or situated outboard of rollers 100 and 101, and an undersurface 87 b that makes engaging contact with rollers 100 and 101. Additionally the undersurface 87 b of belt 87 also contacts top surface 89 of the frame sides 88. As best shown in FIG. 17, top surface 89 of frame sides 88 provides a support surface for belt 87 such that outer surface 87 a of belt 87 is substantially planar and capable of supporting or housing products or items.

A known ratchet type system can be used to advance or move the belt in a desired direction. For example, the ratchet system can include a known non reversible clutch bearing 106 which drives a sprocket 108 having a plurality of teeth 112. The non reversible clutch bearing 106 can be attached to the side panel via one of the pins 99 such that as the clutch bearing is moved in one direction the roller attached to that pin is also moved in a similar direction. The clutch bearing may be moved in a particular direction by a pull handle 110 with rack teeth 112. The system operates in a ratchet-like manner.

As the pull handle is pulled toward a user, rack teeth 112 engage the teeth of clutch bearing 106 to move clutch bearing 106 and, consequently, roller 100 in a clockwise direction to advance belt 87. When the pull handle 110 is moved in toward the shelving unit, the clutch bearing 106 is not engaged and belt 87 is not moved. With respect to the embodiments in FIGS. 13-17, the pull handle is used to move the belt forward by moving pull handle 110 toward the shopper, i.e. in a direction parallel with a shelving unit or the ground. With reference to FIGS. 18 and 19, a different embodiment of pull handle 110′ is shown. In this embodiment, the pull handle 110′ is pulled from an upright position downward in an arcuate fashion, i.e., in a motion similar to the motion of the arm on a slot machine.

In another embodiment, instead of employing a ratchet-type system, the product puller 86, and in particular belt 87 may be provided with one or more slots or openings (such as are shown in FIGS. 1 and 9) which can be grasped manually. In such an embodiment, belt 87 may be moved in a desired direction in a manner similar to the sheet-like structure of the product pullers in the first and second exemplary embodiments.

With reference to FIGS. 15-19, another embodiment of a support frame is shown. In this configuration, a frame side 88′ includes a front leg 124 and rear leg 126, as opposed to flange 94 and cut out 90 shown in FIGS. 12 and 13. As shown in FIG. 16, the frame sides 88′ straddle the shelf beams 120 and 122 of a shelving unit.

The size and shape of a product puller is not critical and a product puller may be sized and shaped to for use on/in shelves of various depths and to accommodate products of various sizes and shapes. For example, with reference to FIG. 20, product pullers of the type described with reference to FIGS. 13-19 are employed in a shelving unit. As shown in FIG. 20, a plurality of product pullers having different widths, W1, W2 are employed to accommodate or match different width packages. For example, the sheet-like structure may be sized as desired to support a particular sized item or package.

A product puller may be separated from an adjacent product puller in any known manner. For example, as shown in FIGS. 18 and 20, a product puller system may employ a known product divider, such as product divider 128 for separating it from an adjacent product puller. In an alternative embodiment, a divider may be attached or fastened to an individual product puller rather than to a shelf.

It will be appreciated that the shelf-like structure may have configurations other than those described herein. For example, and with reference to FIG. 1, the sheet-like structure may have raised sides adjacent the longitudinal sides of the sheet-like structure and perpendicular thereto, so as to define a tray. Raised sides may be integrated with the sheet-like structure or may be separately secured to the sheet-like structure. Such raised sides may be shaped and sized as desired for a particular purpose.

The sheet-like structure of the product puller may be formed from any suitable material. For example, the product puller can be formed from polymeric materials including but not limited to plastics, rubbers, and the like. The rigidity and thickness of the material may vary depending on the type of product which may be placed on the product puller and/or the configuration of the product puller. Generally, in embodiments where the sheet-like structure is to bend or roll up on itself (such as, for example, the product pullers of FIGS. 9-12 and FIGS. 13-19, respectively) the sheet-like structure should be relatively pliable. Additionally, in such embodiments, the sheet-like structure should not be too thick.

The top surface of the sheet-like structure may be made to have a surface with a coefficient of friction that is high enough to prevent packages or containers resting thereon from being slidable on the top surface. Additionally, the bottom surface of the sheet-like structure is made of a material or coating that allows the bottom surface to be slidable along a surface upon which it rests so that the product puller and sheet may be moved along that surface in a desired direction. The bottom surface of the sheet-like structure may contain texture, perforations, embossed features, or the like, to reduce friction, static, and/or vacuum between the bottom surface of the product puller and its supporting shelf-like surface. The two faces of the product puller can exhibit different characteristics.

The sheet-like structure may contain graphics including, for example, product or store logos, or, as shown in FIGS. 1-7 and 11, an instruction, such as, for example, a graphic 39 directing a user to pull at a particular location.

As shown in the various exemplary embodiments a product puller is suitable for use in a shopping or storage environment. In other words, a product puller is suitable for use in either shopping or retrieving items positioned toward the rear portion of a shelf or storage unit by moving the product puller in a direction toward the front of a storage unit, thereby moving the products or items situated thereon toward the front portion of a storage unit. Alternatively, a product puller may be used to restock items in a shelving unit. Items may be placed on a product puller tray end then moved toward the rear of the storage unit by moving the product puller toward the rear portion of the storage unit.

Such product pullers can be useful for moving large, bulky items, such as packages of diapers or laundry detergent, large packages of paper towels or toilet paper and the like toward the front edge of the shelf. In a club or warehouse store environment, which can have particularly deep shelves, such product pullers can find use for moving a variety of packages of goods sold in such stores toward the front edges of shelves.

A product puller has been described with reference to the various exemplary embodiments.
